Ministry of Environment and Forestry Detects 1,331 Hotspots in Indonesia, Most in East Kalimantan (Sunday, September 21, 2025)

Based on the SiPongi forest and land fire monitoring system of the Ministry of Environment and Forestry (KLHK), monitoring in the last 24 hours shows that 1,331 hotspots have been detected in Indonesia. This number of hotspots has increased by 68 points compared to the previous period.

The data is the result of Terra/Aqua, SNPP, and NOAA satellite imagery accessed on Sunday (September 21, 2025) at 11:06 AM WIB. Of the 1,331 detected hotspots, 23 points have a high hotspot confidence level, 1,252 points are medium scale, and 56 points are low scale.

Hotspot confidence levels are divided into 3 scales. Low scale has a range of 0 - 29, medium scale 30 - 79, and high scale 80 - 100. The higher the hotspot confidence level, the higher the likelihood of forest and land fires occurring in a certain area.

The most detected hotspots are in East Kalimantan with 258 points. East Nusa Tenggara ranks second with 144 hotspots. South Sulawesi is in third position with 125 hotspots.

A total of 113 hotspots were detected in Central Sulawesi, followed by West Kalimantan with 113 hotspots, and Southeast Sulawesi and Aceh each having 103 and 82 detected hotspots, respectively.

A hotspot is a coordinate point in an area that has a higher surface temperature than its surroundings, and not the number of forest and land fire incidents.

However, a large number of clustered hotspots in an an area indicates the occurrence of forest and land fires. This means that hotspot data from remote sensing satellite detection is still the most effective in monitoring forest and land fires for large areas.
